The majority of recovered clay tablets date from 1800 to 1600 BCE‚ and cover topics that include fractions‚ algebra‚ quadratic and cubic equations and the Pythagorean theorem. The Babylonian tablet YBC 7289 gives an approximation to accurate to three sexagesimal places (seven significant digits). BABYLONIANS NUMERALS Cuneiform numbers could be written using a combination of two symbols: a vertical wedge for ’1’ and a corner wedge for ’10’. The Babylonians had a sexagesimal

Calculus is the mathematical study of change‚[1] in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations. It has two major branches‚ differential calculus (concerning rates of change and slopes of curves)‚ and integral calculus (concerning accumulation of quantities and the areas under curves); these two branches are related to each other by the fundamental theorem of calculus. Both branches make use of the fundamental

the target of his efforts. After obtaining that important value‚ he determined the distances of the first and third observations‚ and from those the corresponding spatial positions of Ceres. From the spatial positions Gauss calculated a first approximation of the elements of the orbit. Using this approximate orbital calculation‚ he could then revise the initial calculation of the distances to obtain a more precise orbit‚ and so on‚ until all the values in the calculation became coherent with each

When Plato and other prominent philosophers such as Plutarch and Heraclitus were observing the world‚ they came to the conclusion that it was in a state of flux; they came to the conclusion that it was constantly changing. Plato wrote a number of texts including Phaedo and Republic; this worked with his dualistic approach concluding that our realm of appearances – or our world; and all within is changeable and will eventually cease to exist. He says that this world is nothing but a mere copy of forms
